Title: Shield machine
Inventor: YOSHIDA TAKESHI
IPC: E21D9/06
Filed: 1993-12-22
Abstract: PURPOSE:To prevent the traction of a rear carriage from becoming unstable when the excavating direction is changed. CONSTITUTION:A towing device 10 towing a rear carriage 8 from a machine main body 2 is provided with two hydraulic jacks 12, 13 connecting them at separated positions in the horizontal direction and communicating pipes 16, 17 communicating bottom side hydraulic chambers together and rod side hydraulic chambers together. The operating oil is moved so that the oil pressures are made equal between the bottom side hydraulic chambers of both hydraulic jacks 12, 13 and between the rod side hydraulic chambers. The hydraulic jacks 12, 13 are automatically expanded or shrunk to absorb the change of the interval so that the towing forces of both hydraulic jacks 12, 13 become equal, thus the rear carriage is stably towed in response to the change of the course.

Title: Logic simulation device
Inventor: TSUMURA TAKAHIRO
IPC: G01R31/28
Filed: 1990-11-26
Abstract: PURPOSE:To detect a signal after a logic change as logical level variation and to perform accurate simulation by making the logic change of a meaningless signal, generated within a specific time after the start of logic simulation, ineffective. CONSTITUTION:An initial change invalidating means 8 ignores the logic change of the signal within the predetermined specific time, i.e. initial time after the start of simulation as to data on a logic simulation result. A logic change detecting and writing means 9 fetches the logical level after the initial time elapses and writes logical level variation from 1 to 0 when the logical levels before and after the change are 1 and 0, variation from 0 to 1 when 0 and 1, or no variation when the logical level is still 1 in a logical change storage means 4. A logic change display means 7 calculates the rate of terminals where there are logic changes according to the logic change storage table in the means 4 and displays the names of input/output terminals where there is no logic change and the names of their logic components.

Title: Image recorder
Inventor: ENDO YOSHINORI
IPC: B41J2/445
Filed: 1990-11-27
Abstract: PURPOSE:To prevent an exposure time from being prolonged caused by the effect of the responsiveness of an optical shutter by providing a means which attenuates the prescribed quantity of light between a light source and a photosensitive recording medium in the case that the photosensitive recording medium is exposed according to an image signal impressed on the optical shutter. CONSTITUTION:A device which exposes the photosensitive recording medium 7 according to the image signal impressed on the optical shutter 6 is constituted by providing the light attenuation means 23 which attenuates the prescribed quantity of the light between the light source 3 and the recording medium 7. The light emitted from the light source 3 has wavelength required for exposing the recording medium 7 and it is made incident on the shutter 6 through a condensing means 4 as the almost collimated beam of the light. Then, the shutter 6 is controlled according to the image signal inputted from the outside. The expression of gradation density in the image signal can express 256 gradation and the 256 gradation is realized by the light attenuation means 23 by combining three sheets of density filters having different transmissivity. Besides, the total opening and closing time of a liquid crystal cell required for the gradation is made remarkably short in comparison with conventional one. Thus, the exposure time is not prolonged caused by the effect of the responsiveness of the optical shutter.

Title: Drier
Inventor: KAWAHARA SADAO
IPC: F26B25/22
Filed: 1988-12-23
Abstract: PURPOSE:To efficiently dry a material to be dried by setting an operation time by an air intake temperature just after operation start detected by a temperature detection means for detecting the air intake temperature of a refrigerator. CONSTITUTION:An air intake temperature for a refrigerator 6 during initial operation is detected by a temperature thermister 9 to transmit its signal to a controller 10. The controller 10 decides (decision circuit 10b) an operation time for the temperature input by a temperature thermister in accordance with a storage circuit 10a for storing the operation time for a temperature beforehand to actuate an operation timer (operation time set circuit 10c) giving a specified operation time so as to operate the refrigerator by an output relay circuit 10d. In the case where a temperature is low, dehumidification performance is deteriorated to lengthen a dry operation time, in the case where the temperature is high, the dehumidification performance is ensured to shorten the operation time. since the air intake temperature during the initial operation is detected to set the operation time for its value, a material to be dried can be dried efficiently.
